Research on In-situ Calibration Technology for Element Sensitivity of Underwater Linear Arrays
摘要
Abstract
On the basis of calibrating hydrophone sensitivity by the free-field comparison method,a standard sound source method more suitable for in-situ calibration is proposed.This method enables the calibration of array element sensitivity with real-time compensation of environmental parameters,thereby obtaining sensitivity levels better adapted to actual environmental conditions.Compared with laboratory calibration,the proposed method exhibits higher environmental adaptability and practicality.Lake experiments are carried out on a 15-array vertical linear array to verify the performance of the standard sound source method.The experimental results show that the deviation of array element sensitivity levels obtained by this method from those measured by the free-field comparison method under laboratory conditions is mostly within±0.8 dB,with a maximum deviation no more than±1.2 dB,indicating a high consistency between the two methods.The main uncertainty sources are analyzed,and the expanded measurement uncertainty is evaluated as U=1.65 dB(k=2).关键词
